While climate change kills off many species, scientists havefound evidence that it brings genetic changes to others?andthose are the ones that stay healthiest. Can humans use thisinformation to make it through the upcoming climate changes?

Biologist Elizabeth A. Hadly studied two kinds of rodentsfound in Yellowstone National Park in Wyoming: voles andgophers. Both species have survived major climate change.She collected DNA from living animals and compared it withDNA from the teeth of fossilized specimens found in LamarCave. Hadly says, “It contains hundreds of thousands ofbones and represents a continuous fossil record dating back3,000 years. This timescale allows us to really investigatemicroevolution in a natural environment…”

After 30 years in space, America’s oldest spacecraft,Pioneer 10 and 11, are being held back from visiting distantstars by a mysterious force.

Robin McKie writes in The Observer that some scientiststhink this may be the first real evidence of the “darkmatter” that some scientist theorize permeates the universe. A simpler explanation could be that gas from fuel tanks maybe leaking, slowing the craft down. Astronomer MartinBarstow says, “Unless there is really good evidence to thecontrary, we should stick to simple ideas like these and notgo around blaming strange new types of particle or flaws ingeneral relativity.”

Don’t take birth control for granted?there are doctors andpharmacists who want to eliminate birth control pills.

Jill McGivering writes in bbc.com that in the U.S., anincreasing number of doctors and pharmacists are refusing togive women the Pill, saying it’s actually a type ofabortion. While mainstream medicine doesn’t define it thatway, some pro-life professionals do.

Dr. Cynthia Jones-Nosacek, who is a family doctor inMilwaukee, is one of these. She says, “The contraceptivepill doesn’t always prevent ovulation. As often as 30% ofthe time, ovulation may occur and if that happens,fertilization may occur. Then there are other mechanismsthat can prevent that being from surviving. It’s called achemical abortion.”

We’ve recently posted stories about birds and butterfliesmissing from their usual haunts and sometimes turning up instrange places. This could be due to global warming or tothe pole shift now in progress, which will affect migratoryanimals. We’ve also posted a story about leaves changingmuch earlier than usual, which predicts an especially coldwinter ahead. Global warming doesn?t necessarily make thingswarmer?it makes some places colder. And most of all, itcreates weather extremes, as people in the path of therecent barrage of Florida hurricanes have discovered. Weasked for your input so we could find out if these changesin nature are happening where you live as well. To readyour replies,clickhere.
